Drell-Yan dilepton pair production and inclusive direct photon production can be described within a unified framework in the color dipole approach. The inclusion of non-perturbative primordial transverse momenta and DGLAP evolution is studied. We successfully describe data for dilepton spectra from 800-GeV pp collisions, inclusive direct photon spectra for pp collisions at RHIC energies root s- = 200 GeV, and for pp collisions at tevatron energies root s = 1.8 TeV, in a formalism that is free from any extra parameters.
